Normally , i would never use and never recommend any of my friends to use a TG filter. but after reading a few bitogers comments on here, ive been using the TG filter more often. Changed the oil in my buddys 4.3 chevy the other day, told him to get a TG, and another friend also with a chevy he handed me a TG filter to change his oil, usually I would have scoffed and told him to return it, but i spun it on the filter mount without a word. So, are the TG filters not as bad as some think? I still refuse to use an OCOD though.
